The Last IPv4 Address Blocks Allocated

APNIC [Asia-Pacific Network Information Center] has announced that it has received the last two freely available IPv4 address blocks from the Internet Assigned Numbers Authority (IANA). Under the existing plan, IANA will distribute the five remaining address blocks to each of the five Regional Internet Registries (RIR). The RIRs will then distribute addresses within those blocks to organizations within their regions. That means that IANA is out of IPv4 address space, and the RIRs won't be too far behind: "APNIC expects normal allocations to continue for a further three to six months.
